I really appreciate all of the super supportive comments! I felt like I needed a whole post to say so.
Every time I think about what's going on inside of me I feel slightly sick. It feels kind of like a science fiction alien type of thing. But I also think it's all going to work out.
A few things that DH and I talked about before leaving the appointment:
1) We're still glad we transferred 2. Because if just 1 was triplets, we'd have a huge risk of miscarriage as well as a huge risk of a continued pregnancy. So we're glad we have the singleton.
2) We won't decide anything now. We have to see how everything progresses of course. The NP said she had seen the exact same case (once) and that that it resulted in a singleton birth.
A note about selective reduction: it typically takes place during the 12 week. You cannot selectively reduce a "part" of multiples, for obvious reasons.
Let me tell a little more of the "story" now that I got the news out.
The NP that walked in was the funny one which kind of put me at ease, although I felt like puking all day before the appointment. (Nausea or anxiety? Not sure.) She also had an intern with her.
Immediately we saw "something" but it was really fuzzy so I didn't have time to feel relief until we saw the 2 "somethings." We saw 2 eggs sacs right away, right next to each other. When she went to measure the fetal poles, we still didn't see the third. But then Mr. GG saw it, then the intern saw it, then we all saw it - a third heartbeat.
At this point I had no idea they were all in the same sac(?). Then she said "I haven't looked at the other one yet, there are 3 here." And I had to ask her to repeat herself.
When we got to the other side, sure enough, there was another heartbeat.
At one point I laughed. At another, I covered my eyes.
I kept looking at Mr. GG to gauge his reaction, but he had his eyes glued to the screen and just kept asking questions. Mind you this is my husband with whom I agreed to only have 1 child before we got engaged. We have joked about seeing 3 - but like a hilarious impossible joke. 4? Inconceivable.
The ultrasound took A LONG time and they took A LOT of pictures and measurements. I'll put them in another post.
Then finally, we had time to discuss what all of this actually meant.
She was very surprised, but very honest about how rare this is and also how there are no guarantees of what will happen and that weeks 6-8 are the most dangerous weeks (for miscarriage).
Your support means the world to me and makes me hopeful that I might be able to talk about it in the real world. I'll be careful though.
